2\,\text{kg}

block initially at rest is pulled along a smooth horizontal surface by a constant horizontal force of

10\,\text{N}

for a distance of

5\,\text{m}

. Calculate the speed of the block after it has moved the given distance. a)

5.0\,\text{m s}^{-1}

3.2\,\text{m s}^{-1}

7.1\,\text{m s}^{-1}

10\,\text{m s}^{-1}
